Hi friends,

        I’m hoping to be put in the right direction or give me some thoughts on where to start. 

        I returned from a short ride today, about 15 or 20 miles. 
        I noticed at one point in the trip at a stop and later as we backed into the garage a slight gas smell. 
Engine also had a very slight hesitation in reverse.

I check the gas cap and it had no pressure and no smell around it. 

I then decided to pressurize the system.  It was a little hard to hear over the buzzer but I could hear bubbles in the gas tank when pump on. After a few minutes I could turn the key and hear it again.

So, I suspect somewhere air is getting into the system. 

Anyone ever have this happen and where might I start looking or smelling to track this down? 

I have not noticed a consistent or strong gas smell yet but have only started to chase this down.
